1 Correction to: Acta Mechanica https://doi.org/10.1007/s00707-021-03100-7

In the original publication, the captions of figures 3, 4, 5 and 6 are incorrect and they are revised in this correction article.

The correct figure captions are as follows:

Fig. 3 Effect of dimensionless phase velocity \(c/c_1\) on dimensionless wave number \( \bar{k}\) for increasing value of \(\alpha /k\) for model 2

Fig. 4 Effect of dimensionless phase velocity \(c/c_1\) on dimensionless wave number \( \bar{k}\) for increasing value of kl for model 1

Fig. 5 Effect of dimensionless phase velocity \(c/c_1\) on dimensionless wave number \( \bar{k}\) for increasing value of kl for model 2

Fig. 6 Effect of dimensionless phase velocity \(c/c_1\) on dimensionless wave number \( \bar{k}\) for increasing value of \(\bar{\beta }_1\) for model 1

The original article has been corrected.
